Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To prevent heat generated in a dynamic pressure ring from being transferred to a lower surface plate receiver and a lower surface plate, by providing a plurality of strips of grooves in the upper surface of the dynamic pressure ring provided in the lower surface plate receiver positioned under the lower surface plate. SOLUTION: An object to be polished stored in a holder is polished while it rotates and revolves by the action of a sun gear and internal gear between upper and lower surface plates. During this polishing, the lower surface plate, a lower surface plate receiver and a dynamic pressure ring 47 integrally rotate. Annular grooves 80, 81 are provided on the upper surface of the dynamic pressure ring 47, and groove 82 are provided in the circumferential direction, so that a contact surface with the lower surface plate receiver is smaller. The grooves 80, 81, 82 are provided circularly and radially, and area of their escape portions is larger than 70% of the contact area. Therefore, heat generated when the dynamic pressure ring 47 slides against a housing plate is radiated efficiently.

Title: Enhanced spark plug
Inventor: UIRIAMU II RITSUCHIESON
IPC: H01T13/41
Filed: 1991-07-22
Abstract: PURPOSE: To provide a spark plug, which can be manufactured by conventional technology, capable of decreasing energy required for an ignition system by suppressing the generation of electromagnetic radiation at a radio frequency, and capable of reducing erosion and contamination. CONSTITUTION: By reducing capacitance in a spark plug 100, the generation of radio frequency interference(RFI) is suppressed at a low level. Thus, a resistance spark plug is provided to increase the effect of a resistor 140 in the spark plug 100. The reduction in capacitance is achieved because the resistor is provided having a relatively small diameter, and a clearance is produced between a body 112 of the spark plug and an insulating portion 116 with the resistor arranged, and the body is provided extending toward the periphery of the insulator with the resistor arranged. The effect of improving the resistor diminishes the transference of energy beyond the spark clearance, and reduces the erosion of an electrode.

Title: Phase adjustment device
Inventor: WADA MINORU
IPC: H03K5/13
Filed: 1991-08-16
Abstract: PURPOSE:To obtain a phase adjustment device capable of sampling stably a digital data at an FF 2 automatically. CONSTITUTION:A data sampled by a clock CLK1 at an FF1 is inputted to an FF2 as a digital data D2 after a delay time tau1 caused by the propagation of the data through a signal line. On the other hand, the clock CLK1 used for sampling the data at the FF1 is returned to a clock phase adjustment circuit 8 as a clock CLK3 through a delay measurement signal line 7. At this time, the delay measurement signal line 7 is wired so that the delay difference between the clocks CLK1, CLK3 is the delay time tau1. When a clock CLK4 is outputted so that the phase of the clock CLK2 and that of the CLK3 are coincident with each other, a digital data D2 is sampled stably at an FF2 by using the clock CLK2. Thus, the digital data D2 outputted from the FF1 is sampled accurately at the FF2 without causing a phase shift.

IPC: B21D39/00
Filed: 1992-08-03
Abstract: PURPOSE: To provide an internal groove capable of retaining and holding a fixing split ring by deforming a thinned wall body on the split ring maintaining a state that the slit of the split ring is opened in a manner that the split ring can be removed later. CONSTITUTION: In order to form a groove 13 holding a ring 5, first a closing part 6 is suitably arrnaged on a shoulder 4, and then the ring 5 is guided to a thinned part 7 in accordance with the diameter of the inside of the part 7 and the diameter of the loosened ring 5. And the thinned part 7 is pushed down with a tool 9. When the thinned part 7 is guided in the direction of the split ring 5, a force applied on the split ring 5 is orthogonal to a truncated cone-like surface 6 so that the split ring is not closed tightly by sliding over the truncated cone-like surface 6. Therefore, since the inside diameter of the inclined part 7 is slightly larger than the diameter of the closing part 3, it fits completely to the ring 5. If necessary, the groove 13 from which the ring 5 is removed together with the closing part 3 is obtained.

Title: Gas burner
Inventor: ARIYAMA KAZUYA
IPC: F23D14/08
Filed: 1988-08-19
Abstract: PURPOSE:To make a uniform flame length by a method wherein a pair of flame port partition plates present between an outer plate and a U-shaped inner plate are connected only at a lower surface opposing to an end portion of a mixing pipe so as to form a U-shape. CONSTITUTION:Gas injected from a nozzle 12 may suck a combustion primary air through a suction part 5, mixed at a mixing tube 6, its pressure is made uniform at a means pressure part 7 while turning back at the end part of the mixing pipe 6, then the mixture gas is injected at each of the flame ports 8, ignited and burned. At this time, an inner pressure of a burner is high at both ends of the main body 1 of the burner near an inlet port for the mixture gas and the inner pressure at a central part of the burner far from the inlet port is low. However, at both end portions corresponding to the end portions of the mixing pipe 6 of the main body 1 of the burner, a pair of flame port partition plates 4 and 4 are connected at their lower surface 4a, so that the mixture gas strikes against the lower surface 4a so as to prevent a flame from being extended long. In turn, the mixture gas passed by the lower surface 4a floats up from a clearance 11 and goes to each of the flame ports 8. With this arrangement, a flame having a uniform length and stable state is formed and a lifting of the flame in case of low oxygen is prevented.
